[G2 Q&A, Help & Troubleshooting] user2004:
There is a problem with the touchscreen. If i open any menu system settings , over time the touchscreen stops responding to touch. This happens only when the phone is on the table or is on the car holder (i.e. not in your hands). For example, when you start to scroll the list of applications (settings - general - applications - all) after a while everything is locked and it seems that the phone is hung ( there is no reaction to touch ) . Once you take the phone in hand, everything starts to work immediately. At first I thought that it depended on the position of the phone , but then I noticed that if i continue to press the screen with your right hand finger and lean your left hand to it ( to the end , or, for example to the earpiece ) without moving the phone , then the touchscreen immediately wakes up . Once you remove your left hand, the touchscreen freezes once again. With non system applications it is less common . Under these conditions it is not the whole sensor area that freezes , but only the up corner on the right of the screen (it is frozen until you put your left hand on the screen). If not touching the phone wait until the screen turns off, and then double-tap of waking it, then everything comes back to normal for a while. If i hold the phone in hand nothing like this happens and everything works well. The reset of the factory settings did not help. Probably, it has something to do with the ground. If i connect the phone to a usb cord everything is ok. The protective film affects the screen too – without it the screen behaves normally.

Just an update on my G2.

First things first, this past week I cant count how many "4 letter prefixes" I've added to LG. Now that, that is out of the way,I've learned to live with the dead spot by simply rotating to landscape mode for some selections and rotating back for normal use. But now my device has gotten even worse. Not only am I still having the dead spot on the screen, now the phone randomly goes into what I can only describe as "spaz mode". It sounds funny but thats exactly what it does. It basically registers phantom swipes and taps all over the screen. In other words, the phone will dial random numbers, open random apps, etc. All on its own of course. Turning off the screen does nothing. When the screen turns back on it just resumes the spaz mode until it feels like stopping. This happens at completely random intervals. It usually happens in the middle of web browsing, games, and texting. But it's not heat related because it has also happened once immediately after having the phone powered off completely for a few hours. Also, I'm usually inside so my brightness is always between 0%-30%

The worst part about all of this is that I recently left my old job to start something that will pay about 4x the amount I was making before. Of course, they couldn't get in contact with me because of this so that opportunity slipped away and now i'm jobless/broke as hell. But look at the bright side, I have this super awesome $200 LG G2 spaz edition!
[G2 Q&A, Help & Troubleshooting] pokyxda:
Reporting from Singapore, same spazz on day 1.

Phantom clicks, auto close of apps, worse is when i am unable to pick up calls, buttons freeZES.

Also im using phone gps, and i depend on it, so when the g2 spazzes, im lost rhank you very much!

Not sure if u all noticed, the bottom menu keys get lighted up when the ph spazzes, just like it does when u physically touch it. So it will seem if an invisible hand is playing with my phone, home button lits up, ph goes to home screen, home button stays lighted, apps list goes up, apps gets deleted

Its driving me nuts and i am not sure if i shud change a new ph to get the same bloody issue. Was there any LG official comments to fix this?

Btw, i had to retype this 4 times, it shut on me 4 times!!
[G2 Q&A, Help & Troubleshooting] crazysoccerman:
Based on this thread, no one should recommend or buy the G2.

I urge everyone to spread the word far and wide.
[G2 Q&A, Help & Troubleshooting] billykxda:
Agreed that:

- Brightness has nothing to do with this issue. I determined that as well since my last post.

- Very random, but definitely tends to happen after playing a flash video in the browser. This is the only persistent activity within the general category of "just getting busy" on the G2, which was an observation from the start. I'll update the OP to reflect this.

Thanks for your input and clarification.
[G2 Q&A, Help & Troubleshooting] billykxda:
Yikes! Can't say that I've seen or heard of this series of issues with the G2.

Also, the screen protector doesn't have an effect on the issue being discussed in this thread, which is not as severe as what you are living with.

You might want to return that G2!
[G2 Q&A, Help & Troubleshooting] billykxda:
Your series of issues are also more severe than the primary issue being discussed in this thread. Phantom touches discussed here are in response to the user touching the screen and getting additional "touches". Registering phantom touches when not even actually "touching" the phone sounds really bad. Shutting the screen off/on always "fixes" the issue discussed here.

Given your G2's relatively severe symptoms, I would suggest replacing it.
[G2 Q&A, Help & Troubleshooting] billykxda:
Sorry to hear this. As with the previous posts, your situation is also more severe than the primary issue being discussed in this thread, as no one has previously posted that the G2 is registering taps when the user is not already tapping/touching the touchscreen. The "phantom touches" discussed thus far are those that happen in addition to the taps/touches that the user is already doing. Such as the EKG spikes on QuickMemo. Having your G2 automatically making all of the menu selections that results in deleting apps without even touching your G2 has not been reported in this thread, and is definitely reason to consider replacing your G2.
[G2 Q&A, Help & Troubleshooting] vahdyx:
Has anyone discovered a fix yet? I heard that some OTAs have released on these phone I wonder if that addressed the issue.
[G2 Q&A, Help & Troubleshooting] billykxda:
Other than simply turning the screen off/on, which temporarily "fixes" the problem, no - there isn't any persistent/repeatable resolution to this issue as of now.

Everyone's hope is that LG might be listening, and an OTA will address this.

Interestingly, it's been proven that installing an entirely different OS (flashing a custom ROM) on the G2 does not resolve this issue. This indicates that LG would probably need to target a fix to this specific issue, and not just release 4.4.x in hopes that installing a new OS will automagically fix the problem.
[G2 Q&A, Help & Troubleshooting] omegafiler:
I've had recent phones with these type of issues, but my stock LG G2 on Sprint has worked perfectly since day one. I hope others get theirs fixed, just wanted to chime in with my experience.
[G2 Q&A, Help & Troubleshooting] linksmask1:
So the Verizon rep in a post said try safe mode. Of course going into safe mode and looking for the problem is not easy. But is it possible that the problem is caused by some app we all have that's running astray?
[G2 Q&A, Help & Troubleshooting] billykxda:
Many of us certainly have enough bloatware to cause all sorts of problems! But this issue surfaces just fine on G2's that have various custom ROMs installed, most (or all) of which are de-bloated.

With bloatware taken out of the equation, we still have a relatively small number of apps that are installed on G2's regardless of carrier or OS that could theoretically cause problems. But those tend to be apps that all Android devices have installed and are therefore well-known/stable. So, I am not sure if this is a likely cause, but I wouldn't dismiss it entirely.
[G2 Q&A, Help & Troubleshooting] nadrojcote:
How many of you are still using the original film that came on the phone as a screen protector? My friend was and I told her to remove it and hasnt had the problem since.
[G2 Q&A, Help & Troubleshooting] billykxda:
For me, I took that film off immediately. Evidence has shown so far that screen protectors don't have an effect on this issue.

Does this mean that you have the new firmware but are still seeing this issue?

Please clarify!

Thanks.

In addition I have send my g2 to repair but after 2 week i received it back yesterday with the same issue,for the tecnical assistence the phone is ok.i sent in assistence again tomorrow,i am very frustrated....
[G2 Q&A, Help & Troubleshooting] gotwillk:
slightly OT, but seems like its pointless to send your phone back for a replacement/repair if you're not having major issues. if you're having slight spazzes like most people, then i would consider that to be a "good" phone and just stick with it. i have spazzes from time to time and i just turn the screen on and off to correct it. at this point, i've learned to deal with it and not gonna bother sending in for replacement.
[G2 Q&A, Help & Troubleshooting] billykxda:
Over time, I have settled into a position somewhat similar to this.

I LOVE the G2. It offers so much and is, IMO, so far ahead of the pack that I am willing (at times) to put up with some issues, including this one.

But sometimes, this "niggle" becomes a PIA for me, and I am reminded that LG really needs to address this defect.

I guess for me, the frustrating aspects of this defect don't totally go away.
[G2 Q&A, Help & Troubleshooting] Dork6243:
Caught phantom touches on quickmemo. Note the horizontal red lines towards the top. Always happens at the same spot on the screen.

I have had mine now for 6 days and no problems as discribed here:what:
[G2 Q&A, Help & Troubleshooting] linksmask1:
I had mine for a month or two before noticing the issue. Just wait :P
[G2 Q&A, Help & Troubleshooting] billykxda:
I second this!
[G2 Q&A, Help & Troubleshooting] billykxda:
What he said.

In the OP I wrote that there is no need for anyone to report that their G2 is "perfect", because maybe there are "perfect" G2's in the wild that will never, under any circumstance, exhibit this behavior. It's certainly possible. But there are so many variables that can affect the triggering of this defect that it's impossible to know if anyone actually has a "perfect" G2. Maybe just wait a day, week or month? Maybe use your G2 as extensively as those in this thread?

Bottom line is that there really is no way of knowing, so reporting a "perfect" G2 really doesn't further the effort to define this defect.
[G2 Q&A, Help & Troubleshooting] Dork6243:
I was thinking the same thing. But if that were the case, and the device is defective, wouldn't I see the problem carry over into a touch based recovery?

Sent from my VS980 4G
[G2 Q&A, Help & Troubleshooting] crazysoccerman:
I'm really hoping this gets fixed. I want a G2 badly.

If this doesn't get fixed then I'll wait out until the s5 with my gnex.
[G2 Q&A, Help & Troubleshooting] titiwuts:
I can confirm that my previous and current d802 had this problem (only in rare condition).I went to the shop and showed them the problem. They replaced it for a brand new one. I tested it and the problem still persists but in less frequency and doesn't actually affect my daily use so I keep it.

---------- Post added at 11:21 AM ---------- Previous post was at 11:11 AM ----------

Since I've changed ParanoidAndroid rom , I couldn't replicate the problem anymore.

---------- Post added at 11:40 AM ---------- Previous post was at 11:21 AM ----------

Mine happens when the phone lie flat to the ground too after enter the Data Usage setting menu. Even holding the phone parallel to the ground,like 0 degree, can cause it.
[G2 Q&A, Help & Troubleshooting] billykxda:
To be clear, in your experience, this issue surfaces when you:

- Lie the G2 on a table, horizontally

- Choose, "Settings", and then "Mobile Data".

Then, the issue is present?

You get phantom touches, jiggling display, EKG-spikes in Quick Memo, etc?

Does this 10 out of 10 times for you, or something less?

It would be great to hear back from you on this.

To date, no one has reported any truly "repeatable" trigger - one that others can duplicate as well.

For instance, I just tried the procedure above and nothing happened.

Let us know.

Thanks!

[G2 Q&A, Help & Troubleshooting] jonatutu:
I think its the same kind of similar problem but not all entirely. I can draw lines perfectly, no spazz for me.

Its all random sometimes it happen sometimes it dont, I have no way to repeat the problem at will I have try many times. I am on stock no root with developer settings enable option checked are 'shows touches' and 'show touch data'

I only get the problem when I am using the browser ( happen on both stock and chrome )on my phone and with developer settings unchecked (so weird) I thought of checking them and see if it register my touches during the problem but every time I enable them the problem don't occur.

Everything works fine in the beginning, scrolling is smooth, zooming are working properly, pressing the [+] to change to other tabs work fine too. Suddenly the touchscreen wont response, not registering all the touches, I can still scroll but its not smooth, like its been delayed tried scrolling harder as I am frustrated, zooming went weird, 'accidental' press on links will happen. Everything dont work very well now, [+] tab option wont work, even the top notification bar cant be bring down only the Nav buttons are working normally. I have no idea how to fix the problem, but when you know only the Nav buttons are working you will just press home to exit that irritating app. Sometimes it will 'cure' the problem with first try.

But I think I read somewhere, when after long use, phone gets hot, the screen problem occur. It matches my situation to a certain extent, the phone is very hot when it happen, but then again sometimes it don't and with Enabled developer settings never once did the problem occur!!!! \

Hope someone with the same situation can tell me whats wrong. Either software or hardware issue.
[G2 Q&A, Help & Troubleshooting] billykxda:
EXCELLENT!

Can you imagine? VZW was able to identify and fix this issue? I love the idea!! Hope it's true.

I just got this as well. But as we all know, it'll take weeks of ZERO reports to be conclusive.

Here's hoping! Keep your fingers crossed.

Please report back on your findings.
[G2 Q&A, Help & Troubleshooting] billykxda:
As you say, some of these symptoms are "classic" as reported in this thread. You definitely have more variables going on here.

Does turning the screen off/on "fix" the problem temporarily?
[G2 Q&A, Help & Troubleshooting] sickorwuut:
Same issue on my g2. However, I didn't turn the screen off to fix the issue. I simply wipe the screen down, greasy fingers from placing phone on ear, and the problem leaves?
[G2 Q&A, Help & Troubleshooting] billykxda:
Earlier in this thread we discounted cleaning the screen as a "fix" for this issue, as it's not repeatable across owners. If it works for you, notice if your screen turns off in the process.

Turning the screen off/on is highly repeatable for just about every G2 owners that has weighed-in on this issue.
[G2 Q&A, Help & Troubleshooting] Dork6243:
Try removing your sim card, see if the problem persists. Took mine out and havent had one issue. I will be getting a new one this afternoon and will report back. Fingers crossed...
[G2 Q&A, Help & Troubleshooting] Dork6243:
Got a new SIM today. So far so good. The problem with the phantom inputs has disappeared 100%

See, my issues were random scrolling, selection, zooming, and freezing. The freezes were caused by the screen registering multiple phantom inputs. The home screen would swipe and shake rapidly which would make my touch null. Every time this would happen I would open (or try to) launch Quick Memo. Here's what I would see...

These inputs were directly inline w/the bottom edge of the SIM card. Didn't dawn on me until I swapped the SIM back to my other phone and used the G2 without the card. Not sure if it's some sort of digital interference when trying to access data, or maybe related to clearances or tolerances within the phone's SIM tray slot or the card itself...

I'll know more tomorrow evening and will report back.
[G2 Q&A, Help & Troubleshooting] billykxda:
Thanks for sharing and for some great troubleshooting!

Your issue is certainly with the touchscreen, and it's interaction with the SIM apparently, but the focus of this thread is slightly different. Just wanted to clarify that for those G2 owners who are trying to deal with the issue stated in the OP.

Still, it would be great to hear back how this works out for you, so please report back. This is valuable info for those affected by SIM-related issues.
[G2 Q&A, Help & Troubleshooting] billykxda:
It's been two days since the VZW update and I've see no evidence of the touchscreen issue as stated in the OP.

I almost don't want to post this, as I don't want to jinx it! :fingers-crossed:

For other VZW G2 owners that have been plagued by this issue, and have applied the new OTA update, how are you doing??
[G2 Q&A, Help & Troubleshooting] xgman:
I just updated so too soon to tell if my screen issues are fixed, but what it was doing is whenever I tried moving an icon between home screens, it just went into an endless scrolling though home pages and you could not drop the icon in any existing folder. The funny thing is that no such issues crept up using either Nova or Google launcher, just while using the stock LG/Verizon launcher. Fingers crossed.

(by the way, when this happened it was seemingly due to nothing in particular. No excessive pre-use or video or anything like that. Just during random home screen maintenance.)
[G2 Q&A, Help & Troubleshooting] tannor:
I just ordered a LG G2 black will be here tomorrow, just read some of this thread and hope I don't have the issue. It seems whenever I get a new phone I always seem to get all the issues, but that was with samsung, so hoping LG has better QC

I guess I find out tomorrow.
[G2 Q&A, Help & Troubleshooting] robogo1982:
It's great to see an update fixing your problems, since it apparently isn't hardware, you don't have to send it in for repairs and spend days without your phones.

A small, but useful Christmas present, I'd say. :)
[G2 Q&A, Help & Troubleshooting] billykxda:
Agreed! Let's just keep this going!!

I'll feel *really* good about this after a couple of weeks of similar reports from VZW G2 owners.

Ok.... <still holding breath...> it's now 3 days completed with the new update and no sign of this touchscreen defect. I am using my G2 exactly as I always have - rather busy on it - and I am not seeing anything but super fast, super stable performance.

Screen non responsive since VW updater

New to the forum. My wife both have VW stock rom, no rooting has ever been done. My update went through flawlessly but hers is now stuck at "Software update complete" but screen does not let you push OK. KNOCK ON OR OFF does not work as screen is 100% inoperable. Tried holding down power and volume down button and was able to restart and power off phone completely,however, after phone when starts up, we are still getting with that screen. Does anyone know what I can do?
[G2 Q&A, Help & Troubleshooting] Sktr021:
Verizon user here. I had the screeching issue near the speaker on my first device and replaced it immediately. Got my second device and had no issues for 2 days, then I had this screen issue one time. I verified it with the quickmemo trick drawing lines and rebooted my phone. Didn't have any issues. Received the update 3 days later and have yet to have any issues at all so far after a few days.

[Sprint LG Optimus G] samsungepicgeek:
So I just tried updating to ZVC from stock ZVB from this thread,http://xdaforums.com/showthread.php?t=2467897. When it flashed and i was about to reboot from TWRP, it said that there was a problem with root access( obviously) so I clicked the "fix root" button. When I went to the about phone part, it still said ZVB. So I tried rebooting into twrp and i forgot about unlocking the bootloader so i rebooted.I unlocked through freegee, but still no ZVC. So how can I get ZVC? Also, I really dont want to flash any of the ZVC roms, since they require full wipes.
[Sprint LG Optimus G] engine95:
In the root guide, there are instructions on how to do the update. Along with the file.
[Sprint LG Optimus G] samsungepicgeek:
Are you talking about this guide,

Easy to upgrade and keep root, no computer needed!

(I was on TWRP 2.6.3.0 and a stock factory ZVB rom only rooted and unlocked.)

1.) Downloaded VOODOO OTA Root Keeper (Free in market) and FREEGEE. (just in case)

2.) use the Voodoo OTA root keeper to backup root.

3.) Download ZVBtoZVC.zip from Below.

4.) Reboot To TWRP.

5.) Flash ZVBtoZVC.zip

6.) Let Finish And Reboot.

7.)Update PRL's And Profile.

8.)Open FreeGee and Unlock bootloader

I followed this guide but it still said ZVB in about phone.
